One example in my field of engineering is multi-dimensional analysis, where you can design a system (like a machined part or assembly) parametricially and then use an evolutionary model to optimize the design of that part. But my bigger point here is you don't need totally general intelligence to destroy the world either. The drone that targets enemy soldiers does not need to be good at writing poems. The model that designs a bioweapon just needs a feedback loop to improve its pathogen. Yet it takes only a single one of these specialized doomsday models to destroy the world, no more than an AGI. Although I suppose an AGI could be more effective at countering a specialized AI than vice-versa.
